GRAIN-BINDER.-

SPECIFICATION forming part of.Letters Patent No. 594,842, dated December7, 1897.

Application filed February 21, 1893. Serial No. 463,284. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. APPLEBY, a citi zen of the United States,residing in Santa Cruz, in the county of Santa Cruz and State ofCalifornia, have invented certain new and useful Improvements inGrain-Binders, of which the following is a description.

This invention relates to that class of binders now in general use inwhich the grain discharged from the harvester onto a binding-ta ble iscarried wisp by Wisp by packers against a tripping-arm or itsequivalent.

My binder is of the kind in which no clutch is used, but instead onehaving the main gear so mutilated that the driving-pinion passes out ofengagement at the end of each revolution, a provision being made sothat, near the ending of the rotation that binds a bundle, a springshall be put in tension in order that its energy may be exerted to givethe binder enough of its initial movement,when set free by atripping-arm or equivalent device that is influenced by the accumulatinggavel, to carry the'teeth of the mutilated gear into mesh with theconstantly-movin g driving-pinion and thereby cause it to continue themovement first imparted to the said gear by the spring, the object beingto make available a clutching device in such a way that the bindingdevices are started promptly and with a quick movement-that is, actuatethe clutching device such that as little delay as possible shall existbetween the time that the gavel is ready to be bound and the starting ofthe said binding devices. My "construction overcomes the difficulty thatis met with in binding devices having clutches of the ordinary kind inwhich sometimes as much as a half-revolution of the driving-shaft ismade before the said binding devices are started. It is desirable in allbinders, particularly in those that move constantly, that after theproper size of the bundle has once been reached the feeding devicesshould not have an opportunity to bring down still more grain. In thepresent instance not only the mutilated gear is started suddenlyforward, but as the latter is the prime mover of all the parts of thebinder that have to do with placing the band and uniting the same it maybe said that the self-binder practically as a whole is given the initialpart of the rotation required to bind a succeeding bundle.

In the drawings, Figure l is a'sectional elevation showing only suchparts of a grainbinder of the Appleby type as pertain to my invention.several of the parts in their positions after having been given theirinitial movements. Fig. 3 is a section on the line 3 3 of Fig. 1, andFig. 4 is a section on the line 4 4 of Fig. 1.

A is the continuously-revolving packershaft actuated by theharvester-gearing and driving the packers, which may be any of thewell-known kinds.

In Fig. 1 is shown a packer B, (of the kind of which two are generallyused,) which is hung upon a crank on the packer-shaft and which has itslower end held by a swinging link pivoted to the binder-frame. Geared tothe packer-shaft by a pair of bevel-gears, or continuously rotated byany means, is a rap- Fig. 2 is a similar view showing idly-runningdriving-shaft 0, having at its upper end a pinion c.-

D is a mutilated bevel-gear secured to the main shaft and thus adaptedto drive the band-placing, band-uniting, and bundle-discharging devicesand to engage with the continuously-revolving pinion 0 when set free andimpelled by the power stored for the purpose.

The tripping and incidentally the compressor arm F is secured tothe-rock-shaft F, which has suitable bearings in the main frame.Preferably cast integral with the gear D is a cam D, which controls thearm F. This it does in such a manner that the arm mayperform both of itsfunctions, that of a trippingarm and a compressor-arm, preferably in thefollowing manner: G is a lever fulcrumed near its middle in the mainframe at g and having one end, g, adapted to track upon the cam D andthe other end, g linked to an arm II on the rock-shaft F by means of theconnecting device I. In order that the cam may control the lever withthe least friction and the lever also move the cam with the leastresistance, the roller g is provided.

The cam D by the connections above described servesto hold the arm F inan erect position during the operation of packing and compressing thegrain and at the timeimlnediately following the uniting of the ends ofthe band allows it to fall out of the way of the bundle as it is beingdischarged.

The linking device I is made elastic in regard to its length for theusual purpose of preventing undue strain upon the compressingappliances, and, further, its elasticity is utilized by me for formingthe storage of energy I desire for giving the wheel D its initial 1novement when set free by the tripping mechanism. The said linking deviceI may beconstructed in various ways, the most preferable i being thatshown in the drawings, consisting of the rod 1 and the parts shown.

I have thought best to embody the spring above referred to serving as areserve power for giving the binder its initial movement in thecompressor-spring.

Stated shortly, the

compressor-spring may be considered and w ill I be considered in some ofmy claims as having two functions. To accomplish the specific purpose ofembodying my said initial-movement spring in that of the compressor, Iprovide the declivity d on the cam D and so 10- cate thelever G that,with the binding devices in a position of rest, the spring I will beunder tension.

The spring-rod I is hooked into an 3 eye in the arm g of the lever G. Inorder that the spring may be drawn to a state of tension while passingover the declivity (Z, a stop, in this instance the part J, soon to bedescribed, is used. To so resist the action of the spring, I provide thedetent J. For convenience I give the detent the form of a pawl and pivotit on the pin g and thus make the latter serve not only as a fulcrum ofthe lever G, but as an axis of movement for the detent. On the peripheryof the wheel .D is formed a portion of a flange and in it cut the notchJ. In Fig. 2 the detent is shown withdrawn, but it will be readilyunderstood that if the wheel D be turned in the direction indicated bythe arrow and the detent be forced upward at the proper interval its endwill be thrown into the notch. This notch is so placed relative to thespace formed in the mutilated gear that when the pinion is running idlyin the latter the detent shall hold the wheel in that position.Connecting the yoke I of the link with the detent J is the rod J Turningto Fig. 1, it will be understood that the spring 1 being drawn into astate of tension by means of the rod I and the nut 71 a pressure will beexerted to force I upward and force the hook portion of the detent Jinto the notch 011 the wheel and of course hold it there. Although notnecessary it is perhaps proper to mention that while the compressingdevices are permitted to drop, because of the cam D setting the lever Gfree, the detent in this case is dropped far away from the wheel and isfor the time functionless. For the sake of clearness the pinion isomitted from the shaft 0 in Figs. 1 and 2, but

it may be considered as present, as shown in itself to turn the wheel ina forward directionas, let us say, in this instance, byapressure of theroller upon the declivity cZ'--the tripping-arm F being connecteddirectly to the detent J through the instrumentality of a link orlinking device, the movement of the said arm under pressure of the gavelwill draw the detent from engagement with the notch J, which done thewheel willbe started forward by the resilience of the spring and itsteeth forced quickly into engagement with those of the pinion. I makethe notch J of sufficient depth to give an abundance of wearing-surfaceto the working end of the detent, and in order to do so preferably makethe notch J quite deep, so that a considerable movement of the detentwill be required to set the binding devices free. The object of so doingwill be understood if we suppose that the spring I with the parts atrest, is under a certain degree of tension while the grain accumulatesagainst the arm F. Its movement while drawing the detent from engagementwill also increase the tension of the spring 1 which increase of tensionwill find relief only in making still more prompt the initial movementof the wheel D. This desirable result it has seemed to me is most easilyreached by making the one spring I serve the two purposes above referredto. The binding devices once set in motion will so continue to moveuntil the mutilation in the gear reaches the continuously-rotatingpinion. Just previous to such time, however, the cam D forces the leverG to its place of rest, moving the declivity d so far that the pressureof the spring will, indirectly, act upon the decline.

In order to sustain the bearing C for the shaft G at the upper end ofthe latter, a lug is cast upon the frame. A part, however, of the saidlug only is shown and is given the letter M. This is slotted at M, so asto permit the bearing to move. Resting upon the said bearing is thespring h suitably secured at one end to any portion of the framework ofthe machine. N-represents the upper-surface of the binder-table, overwhich the grain moves and on which the bundle is formed.

I am aware that it is not new to so provide in a binder that theaccumulatin g grain shall constitute the motive power that moves thebinding devices forward.
